Engineers at Duke University just proved dead heart muscles in human patients can still be repaired. The fully functioning artificial human heart muscle developed was big enough to patch over damage usually seen in heart attack patients. Ilia Shadrin, a biomedical engineering doctoral student at Duke University, said the patch is a way to replace lost muscle with tissue made outside the body. Current therapies target to reduce the symptoms from the damage caused by the attack to the heart. However, they did not provide approaches to replace the muscle because once lost, it is dead, and it will not grow back on its own. Replacing the lost muscle A scar tissue that could no longer transmit electrical signals or contract often replaces the†¦show more content†¦The Duke University team’s creation is the first human heart patch to meet the two criteria. Nenad Bursac, a professor of biomedical engineering at Duke, said that creating individual cardiac muscle cells is quite common, but the creators should have focused on growing miniature tissues for drug development. It needed a lot of engineering ingenuity to scale it up to the size made by the team on the first time it has been done. Human pluripotent stem cells The cells for the heart patch, grown from human pluripotent stem cells, can become any type of cell in the body. By using different lines of human stem cells, the Duke University team has successfully made patches, including those taken from embryos and those artificially forced or induced into the pluripotent state. There are various types of heart cells grown from the stem cells, like cells for muscle contraction, those that provide the structural framework for heart tissue, and those that form blood vessels. The Duke University researchers placed the cells at specific ratios into a substance similar to jelly where it self-organized and grew into functioning tissue. To find the right combination of cells, nutrients, support structures, culture conditions, and growth factors to grow large, fully functional patches of human heart tissue, it took the team years of work. They sized up and engineered from scratch every container and procedure from scratch.

Youth Policy Kazakhstan Free Essays

Introduction It is 8 o’clock in the morning. The alarm clock rings and everybody in the house wakes up. Kids get ready for school, adults go to work. We will write a custom essay sample on Youth Policy Kazakhstan or any similar topic only for you Order Now Only Almas is not in a hurry, it has been six months since he graduated from university and cannot find a job that suits him. While studying at university everything seemed so easy: â€Å"Graduate, find a good job, become rich†. However, in reality, getting a job came out to be not as easy as he expected. Youth unemployment is one of the problems in the world nowadays. The percentage of unemployed young people in Kazakhstan is equal to 28. 6% (â€Å" †, 2006). This means that the big portion of youth cannot find proper jobs. It is a recognized fact that unemployment is one of the dynamics through which the social condition of a country can be defined. First of all, how can â€Å"youth† be defined? Youth is considered as either a phase of life or as a social category. The phase of life refers to youth being the period between childhood and adulthood. In this report I will consider young people at the age of 20 to 24. Secondly, what is considered as â€Å"unemployment†? According to Investopedia (2012), unemployment is â€Å"when a person who is actively searching for employment is unable to find work†. According to the United Nations Economic Committee for Europe (UNECE, 2011), youth unemployment was one of the drivers of the worldwide financial crisis in 2008. Thus, a governmental youth policy is one of the main policy directions in which a lot of countries all over the world are trying to improve nowadays. The Republic of Kazakhstan is also in the list of these states. The attitude of the Kazakhstani government to young people is seen in the law â€Å"About governmental youth policy† ?581 from 7th of July 2004 (Kazahstanskaya Pravda, 2004). This law points out that youth are the future of the republic and this law is created to reduce the number of unemployed youth. According to the Agency of the Republic of Kazakhstan (2003) the percentage of youth of the overall population was equal to 29. 1% in 2003 (cited in: A Social Portrait of Young People in Today’s Kazakhstan, 2006). This means that the youth is a significant fraction of the country’s population. Nowadays, young people face difficulties in receiving health service, good education, employment housing and other social issues. By providing support to this portion of the population and paying more attention to the development of youth policy, the Kazakhstani government could give the country an opportunity to build the basis for the brighter future for Kazakhstan. The main research question of this report is: What factors are contributing to youth unemployment? I will be investigating the reason young people cannot find jobs; despite the fact that the government is making everything they can to reduce the number of unemployed young people. As I am graduating soon this issue has a direct connection to me, so I also want to find out what can I do to avoid this problem. In order to answer the key research question I will follow the three research objectives. Firstly, as I have written in the previous paragraphs young people have a huge influence on the economy of any country. That is why I will analyze the current economic, social and political situation in Kazakhstan. Secondly, I will estimate the effectiveness of youth policy of the government in Kazakhstan. Finally, I will consider the opinions of young people on the issue of youth unemployment. The research project will consist of a survey and interviews. Questionnaires will be distributed among the alumni students of universities as Kazakhstan Institute of Economics, Management and Strategic Research (KIMEP), University of International Business (UIB), Kazakh-British Technical University (KBTU) and others. The reason I’m choosing exactly Kazakh-British Technical University (KBTU) and others. The reason I’m choosing exactly this kind of survey is that results are likely to be objective because of to the anonymity of the surveyed people. Moreover, through questionnaires I will be able to gather information from a significant amount of people in a short time. The surveys are planned to be held during the midterm break (October, 2012). The representatives of such governmental youth organizations such as KIMEP Students Association (KSA) and â€Å"Zhas Otan† Youth Political Party will be interviewed. I will interview them, as they know the problem from the inside: from the governmental point of view. Also, they are university graduates, so they can analyze the problem by combining the two different sides. Interviews are helpful, as during the interview I will be able to ask questions I’m interested in and find new information from the knowledge and experiences of the representatives. Interviews will also be held in October, 2012. The first paragraph of this report gives information on the general background of research problem and also identifies the main research uestion. Moreover, introduction includes the short description of the research methods. It also consists of the work plan. The second section addresses the literature review, which is based on the information collected from academic articles of Google Scholar databases, EBSCOhost, magazines, Kazakhstani newspapers, different Internet resources, and books. The third chapter covers the data and methodology informat ion. The next chapter focuses on the analysis of received data and its discussion. The last chapter is the conclusion. It summarizes the done work. The sources used and gathered are provided in the bibliography section. Each section is approximately from four to seven pages. References: Eshpanova D. D. Nysanbaev A.

Road to Revolution Essay Example For Students

Road to Revolution Essay The Road to a Revolution The American Revolution was a major event, which resulted in America gaining its freedom from England, during the last half of the eighteenth century. From the very founding of each settlement, America promised people a new life in which one could live in happiness without being prosecuted. The founding fathers of America knew the potential the colonies had to offer to its people and chose to fght against the British for freedom. Many events had occurred that lead the colonies right to the moment they declared their independence. In 1754, the French and Indian War began, which resulted in the British taking control of North America. Its high expense laid the foundation for conflict that resulted in the choice to declare independence from Great Britain. After the French and Indian war ended in 1762, the Proclamation of 1763 was issued, which stated that none shall pass beyond the Ohio Valley, resulting in the colonies to be outraged. The settlers were in the midst of Pontiacs Rebellion, which were a series of raids from Indians. The Proclamation of 1763 caused the colonists to get angry, because hey could not protect themselves, since the British could not afford to build forts for the protection of the colonists. George Grenville became Chancellor of the Exchequer in 1763, and he allowed not only direct taxes, but indirect taxes as well. This lead to his choice on the creation of the Sugar Act and the Stamp Act. Grenville knew the colonies needed to find revenue, and charged taxes on molasses and all paper products used for official documents. The Sugar Act in turn regulated trade and did little to raise revenue, as planned. The Stamp Act resulted in many who resisted, and ell toa repeal in 1766. In 1765, the Quartering Act was introduced, which claimed that British troops could live in peoples homes if needed. Also in 1765, the British composed the Writs of Assistance, which allowed the British to look through any paperwork. Both the Quartering Act and Writs of Assistance left the colonists to feel used by the British, while also being left with no privacy. Another event in 1765 added to the growing tension between Great Britain and the Colonies. Colonists were attempting to dock at Ft. Johnson, South Carolina, and the British refused them. This aused the Colonists to take over the fort. The Townshend Acts were created in 1767, which was a British law that established a tax on all tea, glass, lead, paper, and paint imported to the colonies. This act also added to the tension growing between the Colonies and the British. The Townshend Acts lead the colonies to a boycott. Then in 1768, there was the Circular Letter which stated the colonies needed to unite against Great Britain. All these acts lead up to the Boston Massacre in 1770. Although only 5 died during this event, it was one of the first violent acts made against the British during this time f major changes imposed to the colonies. Also in 1770, the Townshend Acts were repealed, and lead toa boom in trade until 1771. In the following year, the royal Navvy ship Gaspee burned down, which resulted in Great Britain raising their fences against the Colonies. In 1773, England imposed a new tax on tea, which lead the Three ships containing tea arrived, where they were denied access to the dock, unless the revenue was repealed. The British ships wouldnt back down, which lead to a large crowd gathering, and anticipating their next move. Shortly after, 100 to 1 50 en disguised as Indians boarded the ships, while dumping hundreds of pounds of tea into the harbor. This event lead to the British closing the Boston Harbor, until all the wasted tea was paid for. .u1f848aa22707a4c50d0de0dc505a233b , .u1f848aa22707a4c50d0de0dc505a233b .postImageUrl , .u1f848aa22707a4c50d0de0dc505a233b .centered-text-area { min-height: 80px; position: relative; } .u1f848aa22707a4c50d0de0dc505a233b , .u1f848aa22707a4c50d0de0dc505a233b:hover , .u1f848aa22707a4c50d0de0dc505a233b:visited , .u1f848aa22707a4c50d0de0dc505a233b:active { border:0!important; } .u1f848aa22707a4c50d0de0dc505a233b .clearfix:after { content: ""; display: table; clear: both; } .u1f848aa22707a4c50d0de0dc505a233b { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u1f848aa22707a4c50d0de0dc505a233b:active , .u1f848aa22707a4c50d0de0dc505a233b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u1f848aa22707a4c50d0de0dc505a233b .centered-text-area { width: 100%; position: relative ; } .u1f848aa22707a4c50d0de0dc505a233b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u1f848aa22707a4c50d0de0dc505a233b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u1f848aa22707a4c50d0de0dc505a233b .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u1f848aa22707a4c50d0de0dc505a233b:hover .ctaButton { background-color: #34495E!important; } .u1f848aa22707a4c50d0de0dc505a233b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u1f848aa22707a4c50d0de0dc505a233b .u1f848aa22707a4c50d0de0dc505a233b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u1f848aa22707a4c50d0de0dc505a233b:after { content: ""; display: block; clear: both; } READ: Fences Vs A Lesson Before Dying EssayGreat Britain also altered the charter for Massachusetts, leading to Parliament gaining control of Massachusetts. The third act put in place was known as the Impartial Administration of Justice Act, which stated although the men were tried for the Boston Tea Party, they still had to be tried for court in Britain as well. The fourth act was the Quartering Act, and the fifth act was the Quebec Act. These five acts are what history calls the Coercive Acts, or the Intolerable Acts. In 1775, Massachusetts was declared to be in a constant state of rebellion against the British, and then lead to the Battles of Lexington and Concord, which mark the very beginning of the American Revolution. The colonies were refusing to be under the control of Great Britain, and lead to the declaration of independence of America. The British pushed the colonies too far with all the taxes and laws when the Colonists came to the New World to escape these restrictions.
